Production And Processing of Bicycle Frame Parts

Last Updated on October 12, 2023 by assistant


With the progress of the times, modern people’s pursuit of environmental protection is getting higher and higher, and the appearance of bicycles makes them the most sought after means of transportation in the new era. However, bicycle components vary to varying degrees depending on the specific type and its intended use. In this blog, I mainly take you through the manufacturing and production methods of bicycles – structural parts of bicycle frame parts.

The frame is the main structural part of a bicycle and is usually made of metals such as steel, aluminum or carbon fiber. Each manufacturing material corresponds to a different manufacturing process. In the prior art, the bicycle frame made of aluminum alloy is basically connected with various components on the bicycle through a welding process. This process generally requires cutting, deformation, welding, grinding, heat treatment and other processes. But the traditional manual operation is difficult to guarantee the consistency of batch quality;

With the progress and development of science and technology, CNC machining has entered our field of vision. Bicycle frames currently on the market can easily manufacture complex bicycle frames through CNC machining centers. In addition, the frame produced by CNC machining is not only superficial. Smoothness can also improve the strength of the frame to a certain extent, increasing the risk of structural failure. The surface treated frame will have a great improvement in appearance.

Currently popular manufacturing methods

#1 Steel Tube Construction
Traditional bicycle frames are usually made of steel tubes. The method involves cutting and welding steel pipes together to form the frame. It has good strength, durability and ride quality, but it can be relatively heavy compared to other materials.


#2 Aluminum Extrusion Profiles
Aluminum is a lightweight material commonly used in the production of bicycle frames. These frames are manufactured by extruding aluminum alloy tubes into the desired shape and joining them using techniques such as welding or gluing. Aluminum frames are known for their light weight, high stiffness and corrosion resistance.


#3 Carbon Fiber Composites
Carbon fiber frames are popular for their superior strength-to-weight ratio and stiffness. Sheets of carbon fiber are layered and glued together using resin to form the frame. This process allows precise control over frame characteristics. Carbon fiber frames are lightweight and generally provide a superior ride quality, but they can be more expensive to produce.


#4 Titanium welding
Titanium frames are known for their superior strength, durability and corrosion resistance. Titanium tubes are cut and welded together to form the frame. Titanium frames provide a smooth ride quality and are relatively lightweight compared to steel frames.


#5 Molded Carbon Fiber
Some high-end bicycle frames are manufactured with molded carbon fiber construction. The method involves using a mold to shape layers of carbon fiber and resin into the desired frame shape. The process allows for complex geometries and optimized frame designs. The molded carbon fiber frame is lightweight, stiff and offers excellent vibration dampening properties.


Final Thoughts

At present, there are various bicycle frames for sale on various platforms, with prices ranging from a few hundred yuan to tens of thousands of yuan. If you buy directly from the platform, it will increase a lot of cost, so why not choose to cooperate directly with the manufacturer and get the factory service directly.
